several procedures have been developed to obtain these compounds. The present study aimed to synthesize 17 derivatives of isoxazol-5(4H)-ones using a multicomponent reaction catalyzed by an acidic ionic liquid, which allowed yields from 20-96% of the products. To evaluate the bioactivity of the compounds, the synthesized derivatives were analyzed at various concentrations against bacteria and fungi;
